Referring to Fig. 1 of the drawings, 1 denotes the engine or propellershaft or a counter shaft driven from the engine or propeller shaft andprovided with beveled gear 2 meshing with a. beveled pinion 3 carried onone end of a counter shaft 4t. Upon the other end of the counter shaft 4is socured at pinion5 which meshes with a gear 6 carried by sleeve '7.Extending through the sleeve 7 is a. rotatable and longitudinallyshiftable spindle 8 provided with a feather and surrounding the spindle8 between the collars 10 and 11 is an elongated sleeve 12 formed with ahelical. groove 1'3. The sleeve 12 is loose on the shaft and hes mountedthereon in proximity to the collar 10 a flanged annular memberl4lprovided with apertured lugs 15 to which pivoted links 16; Upon thesleeve 3. in proximity to the collar 11 is mounted a band 17 havingapertured lugs 18 to which are pivoted the links 19. otelly securedtogether ant... to the weights or balls 20 as at interposed between themember 14.- and the band it? is coil spring 22 which surrounds thesleeve The spindle 8 carries pin 23 which travels in the groove 13whereby onthe rotation of he spindle 8 the governor mechanism consistingof the elements 14- to 21 are operated. Carried by thcspindle 8 is agrooved collar in which extends a pin projecting from the lower arm of abell crank lever 26, said arm liciilg indicated by the referencecharacter 27 while the upper arm of the bell. crank lever 26 isindicated by the reference character The lever 26 is pivoted as at 99 toa hangz er 30. The arm 28 of the bell crank ever 26 pivotally connectedby the pin fit to a linl; 82 and to a sliding block 33 shittahly mountedwithin a curved (lot 3% litn'med in :1 curved link 85 pivotedintermediate its ends as at 36. The reference character 37 denotes alink carrying a pin 38 whicl i is attached to the lower portion ot theslot 3% of the link 3-). The link. 37 is pivotally attached as at 38 toanangle-shaped shiiltlug member, the horizontal arm 3? thereof beingpivoted to the link 3'? and e tcnding" through the guide 40 while thevertical arm .1-1 of said shifting member extends between the flange ofthe member 14. and one oi? 'hc lugs 15. The foregoing constructionconstitutcs an operating means actuated from the engine for operatingthe recording device as well as the indicating mechanism and is used inconnection with either of the indicating mechanisms shown, that is tosay, the indicating mechanism shown in Fig. 1, as well as that shown inFig. 2 and l The operation of this operating mechanism will behereinafter referred to in connection with the separate forms of theindicating mechanisms as well as the recording device. As the samerecording device is wed in connection with any of the forms of theindicating mechanisms shown, it is only illus trated in connection withthe form oi indicator shown in Figs. 1 and 2, but it is applicable tothe form of indicator shown in Fig. 3, and it will now be described.

Referring to Figs. 1, 3, l1 and 7, in which is shown thercm'ndinodevice. or elements thereof, 42 denotes a supporting plate canrying a clock train 4:3 for operating "the spindles 4 and 45 forunwinding the record These latter and the links 16 are piv-. I

ec oes tape 4-6 from the reel 47. A receiving spool is indicated by thereference character &8 and which is driven from the clock train and uponwhich is wound the tape as it leaves the rolls 41-9 and so. The guidefor the record tape indicated by the reference character 51. The recm'dtape 46 is formed with a series of longitudinally and trans verse linesand 53 whereby vertical columns of spaces and longitudiniilly extendingrows of spaces are provided. By way of example, each space indicates aminute and centrally oi the tape a divisional. line as 'at is providedto indicate stop. The tape adapted to have recorded thereon the huml oirevolutions of the engine shaft whether the engine running ahead orback, the tape being divided into two sec tions by the line 54, onesection to indicate ahead at 55 and the other back as at- 56. Thesection divided to indicate a quarter speed, one-halt" speed ahead,threequartcrs speed ahead, and full speed ahead, 'tl'icscction 56 beingalso divided to indicate one-quarter speed hack, one-halt speed back,three-quarters speed hack, and full speed back. The inner longitudinalrow of spaces of each section is designed to indicate tenI'QVQlHlIlOI'LS oi? the engine shaft, the indications increasingoutwardly, for example, the inner row would indicate 10 revolutions andadjacent row 20 and. so on, the maximum speed being, by way of example,one hundred. The indications for both sections ahead and back aredesignated by reference character 57. By the foregoing arrange ment arecord can be made upon the tape of the exact number of revolutions theengine sha making, whether the engine is runni ahead or back, or whetherthe engine at stop and the duration of time the engine rcn'iains at stopqr travels ahead or back. Associating with the tape 16 is a marker 58which. operates transversely of the tape to be positioned so as toinscribe upon the tape a record in the form of a longitudinal. line at apoint between the longiludiinil lines 53 upon the tape. or upon the lineThe marker 58 is carried by a .rcciprocatory arm 5!), the latter slidesthrough a guide 60 and is pivotally con uected by the pin (51. to oneend. of the link 3.2. The tape 46 through the medium of the clock train-18 travels at a predetermined rate ot speed and even though the engineis at stop the marker 58 will. record upon the tar the duration of thestoppage.

The manner in which the arm. 59 is operated so as to inscribe upon thetape a record oi" the action oi tl'ieeng'ine is as follows: 'llhcsliding spindle 8 being driven from the shalt l, the governor operatedthrough the medium of the pin 23 in the direction of thoarrow A, whenthe balls or Weights 20 site thrown outward by tin; contracting links 16and 19, the member 14 is shifted toward the band 17 or in other wordsslides to the left carrying the shifting member therewith, such actionof the shifting member rocks the link 35 on its pivot 36, the link 35shifting the link 32 whlch moves the arm 59 toward the innerlongitudinal edge of the tape carrying the marker therewith, the markerbeing shifted to one of the longitudinal rows of a section of the tapewhich indicates back and on which a record is made. When the enginereverses the sliding spindle 8 will not shift the governor until the pin23 moves through and to the left end of the groove 13, and by this timethe sliding spindle 8 will have moved from arrow Y to arrow X actuatingthe bell crank 26 and shifting the pivot 31 to the upper end of the slot3a in the link 35 so that when the flanged member 1 1 is caused to againmove tothe left by the operation of the governor, the marker 58 will beshifted by the arm 59 to the ahead section of the tape, making thenecessary record thereon in one of the rows of spaces of said section.

Referring to the indicating means shown in Fig. 1 it embodies a primaryand a secondary indicating 1nechanism,-each formed of an indicatingplate, the plate for the.

primary being indicated by the reference character 63 and the plate forthe secondary by the reference character 62, the plates 62 and 63 areprovided with corresponding indications 64 divided into two divisions,one ahead as at 65 and the other back as at 66, these indicationsdesignating the speed of the engine shaft or other desired matter.The/plate 62 is arranged in the pilot house, and the plate 63 in theengine house, and associating with'the indications upon each plate is apointer 07 mounted upon a shaft 68 carrying a ratchet wheel 69. Theratchet wheels 69 are connected together I by a belt 70 or othersuitable means whereby on the movement of the lower one of the shafts 68motion will be transmitted to the upper one of the shafts and thepointer carried by this latter shaft will be shifted. The pointer 67 forthe plate 63 is connected by the pin 61'to the arm 59 and lever so thatwhen the operating mechanism for the recording device is actuated, suchoperating mechanism also constituting the operating mechanism for theindicating mechanism,

the dial (37 of the plate (33 is shifted to indicate ahead or back asthe case may be. as well as indicating the number of revolutions of theengine shaft. W hen the said pointer 67 of the plate 03 is shifted theshaft 08 to wliiehsaid pointer is attached is rocked and whichffhroughthe medium of the transmission 7'9 will actuate the shaft (58 for thepointer 67 of the plate 62 so that itwill be indicated in the pilothouse in what direction the engineis running and also the speed andone-quarter speed hack.

of the engine. The same indication will be had in the engine room aswill be evident.

In a combined recorder and indicator in accordance with this inventionthe indicator may be a mechanical one or as shown in Figs. 2 and 3 anelectrical one, the description of the electrical indicator shown inFigs. 2 and 3 will now be described. Such construction of indicator canbe used in lieu of the form shown in Fig. 1.

Referring to Figs. 2 and 3 of the drawing 71 indicates a supportingplate which is arranged in the engine room and has pivoted thereto as at72 a pointer 73 to, which is pivotally -connected as at 7 1 the arm 59and link 32. By such an arrangement it is evident that when the link 32and arm 59 is actuated, the pointer 73 will be shifted, the shifting ofthe pointer is for the purpose of closing an electrical circuit to causecorresponding visible indications, so that the engineer as well as thenavigating oiiicer can ascertain in what direction the engine is runningand at what speed, or tovisibly indicate any other correspoinlingindications desired.

which means that the engine is running backward, ahead as at meaningthat the engine is running ahead. Associating with the indication backare the following indications: full as at 77; threequarters as at 78;one-half as at 79; and one-quarter as at 80. The indications 77 to 80mean full speed back, threequarters speed hack, one-half speed back,Associating with the indication ahead are the following indications:full as at 81; threequarters asat 82; one-half asat 83; and

one-quarter as at 84; and whichmeans full speed ahead, three-quartersspeed ahead, onehalf speed ahead, and one-quarter speed ahead. Duplexindications 7,3 to 84 are employed, one set as at 8:) in the pilothouse, and the other set as at 86 in the engine room. The indicatingmeans located in the engine room is termed the primary indicatingmechanism and the in'dicating means located in the pilot house is termedthe secondary mechanism. Each of said. indications are carried by atranslucent or opaque element 87 with the indications so arrangedthereon as to be transparent, so that when a lamp is illuminated at theback of the translucent elements the indications will. be visible. Foreach indication there is av lamp. The circuits in connection with thelamps will. now

be referred to. The plate is provided with By way of example, theindicatrons shown are to 1nd1cate back as at 75 engine room. The lamps88 and 99 to 103 J are connected to the lamps 105, 106, 107, 108,

109, 110, 111, and 112 by the branch wires 113. The lamps 105 to 112 arearranged at the rear of the indications 77 to 84 which are in the pilothouse. At the rear of the indications 75 and 76 which are in the pilothouse are arranged lamps 114 and 115, and at the rear of the indications75 and 76 within the engine room are arranged the lamps 116 and 117. Thelamps 105 to 108 are connected to the lamp 114 by the branch wires 118and the lamps 109 to 112 are connected to the lamp 115 by the branchwires 119. The lamp 114 is connected to the'lamp 116 by the branch wire120 and the lamp 115 is connected to the lamp 117 by the branch wire121. From the lamps 116 and 117 lead thQyClI'Clllt wires 122 and 123respectively, which are connected to the source of electrical energy124. From the source of electrical energy 124 leads the branch wire 125which is connected to the pointer 73. It the pointer 73 be shifted toengage the contact 92 the lamps 100, 109, 115, and 117 will beilluminated whereby the indication one quarter speed ahead will bevisible, the indication not only being visible in the engine room, butalso in the pilot house, and also remains visible until the pointer 73is shifted from engagement with the contact 92. \Vhen the pointer 73 isin engagement with the contact 92, the circuit will be from electricalsource 124, wire 125, pointer 73, contact 92, through the lamp 100,branch wire connecting lamp 100 and lamp 109, branch wire 119 connectinglamp 109 with lamp 115, branch wire 121 connecting lamp 115 with lamp117, and from. lamp 117 by branch wire 123 to electrical source 124. Thelamps 115 and 117 will always be illuminated when the pointer 73 engageswith any of the contacts 89 th 92 as will be evident, and the lamps 114and 116 will always be illuminated when the pointer 73 engages any ofthe contacts 93 to' 96. It is thought unnecessary to describe eachcircuit as the various circuits can readily be understood from thedescription of the circuit referred to. lVhen the circuit is closed tovisibly indicate the direction in which the engine is running and thespeed of the engine, the arm 59 is also shifted so that the record ismade upon the tape 46, the record being made simultaneously with theoperating of the indicating mechanism.

The modified form of indicating mechanism shown in Fig. 4 comprises apointer 126 pivoted as at 127 and to which is also pivotally connectedas at 128 the arm 59 and link 32. The pointer 126 is provided with apair of contacts 129 and 130, the former adapted to engage the contactpoints of the set 131 or of the set 132, each of the contacts of the set131 being connected by a branch wire 133 to the resistance 134 which isconnected to the electrical source 135 by the branch wire 136. Arrangedin operative "relation With respect to the pointer 136 are the contactstrips 137, 138, 139, 140, and 111. The contact strip 137 is connectedto the strip 140 by the bridge 142, and the contact strip 138 isconnected to the contact strip 139 by the bridge 143. The contact strip141 is connected by the branch wire 143 and 144 to a resistance 145which is connected with the electrical source 135. The set of con tacts131 associates with the scale for indicating that the engine istraveling ahead as well as the revolutions of the engine shaft. The setof contacts 132 associates with the scale 147 for indicating that theengine is running backwardly, as well as the revolutions of .the engineshaft. The scales 146 and 147 are arranged in the engine room and withinthe pilot house positioned a miliammeter 148 provided with scalescorresponding to the scales 146 and 147. between the contact strips 139and-140 and the miliamnieter are indicated by the reference characters149 and 150. The pointer 151 of the miliammeter associates with thescales 152 and 153 of the said meter, such scales' as before statedcorresponding to scales 147 and 146. Each contact point o1 the set 131associates with a graduation oi the scale 146 and a like arrangement ishad in connection with the set of contacts 132 with respect to thegraduation of the scale 147. The electrical circuit for ahead is asfollows: It will be assumed that the pointer 126 has been shifted toengage one of the contacts of the set 131, the circuit would then befrom the battery 135, wire 136, contact point 131, contact 130, contactstrip 137, bridge 142, contact strip 140, wire 150, to miliammeter 148,through the meter, back over Wire 149, contact strip 139, bridge 143,contact strip 138, contact 129, contact strip, 140, wire 144, resistance145, to battery 135.

The set of contacts 132 are cross-connected with the contact points ofthe set 131 in the manner as indicated by dotted lines 154 in Fig. 4.This same arrangement is carried throughout with respect to the contactpoints of the set 132. The backcireuit is as follows: It will be assumedthat the pointer 126 has been shifted to engage one of the points of theset 132, the circuit is battery 135, wire 136, resistance 134, one ofthe cross.

wires 154, contact point of the set 132, contact 130, contact strip 139,wire 149. the miliammeter 148, through the latter, back over wire 150,contact strip 140, contact 129.

contact strip 14], wire 144, resistance 145, to battery 135.

In the form shown in Fig. 4 when the pointer126 is shifted to engagethat contact- The electrical. wire connections senses such informationwill also be furnished to "the navigating oiiicer owing to the operationof the miliammeter. H the pointer 12% should be shifted to engage one ofthe contact points of the set 132, say that contact pin is at theindication 60, the engineer will be informed that the engine is runningbackwardly and that the engine shaft is revolving sixty revolutions. Assuch operation on the part of the pointer 126 will close the circuit,the miliainnieter will be operated and the navigating oliice'r upon. in-

spection of the miliammeter can also ascertain the action otthe engineas well as the speed. When the device shown in Fig. 4 is operated, toindicate ahead or back, as well as the speed of the engine, therecording device is simultaneously operated as the arm. 59 is shiftedwith the pointer 126.

In Fig. 5 of the drawings, a vessel is shown diagrammatically asprovided with a series of indicating mechanisms-whereby they will all besimultaneously operated when the pointer 155 is shifted to engage acontact 156. The "form of indicating mechanisms the lamps at the rear ofthe inscription ahead employed is similar to that shown. in Fig. 2. Thecircuit connections being such as to cause a simultaneous operation ofthe indi cat-01's. The indicators are arranged in the engine room, atthe port side ofthe vessel, at the stern, at the starboard side, on thebridge, and in the pilot house, and are indicated respectively by thereference characters 157, 158, 159, 160, 161, and 162. "he source ofelectrical energy is indicated by reference character 163. it is thoughtunnecessary to trace all of the circuits in connection with the variouslamps for the various indications as it is thought that the circuits canbe fairly understood when but one circuit is traced. It will be assumedthat the pointer 155 has been shifted to engage a contact 163, thecircuit will be battery 153, pointer 1555, contact 163, branch wire 16i, lamp 165, branch wire 166, lamp 167, branch wire 168, lamp 169,branch wire 170, lamp 171, branch wire 172, lamp 173, branch wire 174:,lamp 175, branch Wire 17 6, lamp 177, branch wire 178, lamp 179, branchwire 180, lamp 181, branch 182, lamp 183, branch Wire 184, lamp 185,branch wire 186, lamp 187, branch wire 188, battery 163. This willnot.only illuminate the lamps at the back of. the correspondingindications for indicating full speed ahead or otherwise, but will alsoilluminate hr backas the case may be. When the circuit is closed therecording device is also thrown into operation through the medium ofthe. link 32 and arm 59. With the foregoing arrangement an ollicer canascertain at various points upon the vessel what the engine is doing. 1.

The combined recorder and-indicator not only acts as a check upon theengineer but also the navigating officer in case he should give a wrongorder. In this connection it will be assumed that the navigating ofiicertelegraphed to the engineer through the medium of the ordinary shipstelegraph full speed ahead. The engineer responds promptly andcorrectly, the navigating oilicer by referring to the indicatingmechanism can ascertain whether the en ineer has correctly carried outthe orders, it not the indicating mechanism would show it.

From the foregoing construction and arrangement of parts, it is evidentthat a means is set upwhereby a navigating officer as well as theengineer can ascertain what the engine is doing and that furthermore apermanent record is made of the actions of the engine and which can beused in case of a dispute. This permanent record being made by, arecording device actuated from a moving part of an engine. The actuatingmechanism for the recording device as well as for the indicatingmechanism being common to both and is operated as afore stated,from amoving part of the engine, and not manually.
